Definitions

  • the present invention relates to dual light source lamps. Specifically the present invention relates to a glow discharge lamp and an incandescent lamp that are disposed within the same envelope and function independently.
  • An incandescent lamp includes an incandescent filament (usually tungsten) disposed within an optically-transmissive envelope.
  • the envelope contains an inert gas such as argon, nitrogen, neon or krypton to reduce the rate of evaporation of the filament material.
  • a glow discharge lamp includes an optically transmissive envelope containing a noble gas and electrodes. When a voltage is applied between the electrodes, a glow discharge is formed.
  • Incandescent light sources and glow discharge light sources have been used in a co- dependent manner in the lighting art. United States Patent No. 5,066,892 issued Nov.
  • FIG. 1 is a cross-sectional view of a first embodiment of a dual-type light bulb according to the present invention.
  • FIG. 2 is a cross-sectional view of a second embodiment of a dual-type light bulb according to the present invention.
  • FIG. 1 a diagram shows a first embodiment of a dual-type light bulb 10 according to the present invention for providing a plurality of light sources within the same envelope.
  • a base 12 is threaded and configured to fit in a standard three way incandescent socket, and provides both support and electrical contacts 14 and 16 to filament 18.
  • Electrical contact 14 may be electrically connected to the threaded shell of base 12, and electrical contact 16 may be an annular ring (thus shown as two cross sections in FIG. 1) electrically insulated from the shell of base 12 as is known in the art.
  • filament 18 is a standard incandescent filament.
  • Filament 18 is disposed in an optically-transmissive envelope 20, usually formed from a glass material.
  • Envelope 20 contains a noble gas and is hermetically sealed to base 12 as is known in the art.
  • glass envelope 12 also contains a glow-discharge lamp 22.
  • the envelope 20 is filled with neon gas and the glow discharge lamp 22 comprises two electrodes.
  • One of the electrodes 24 is electrically connected to electrical contact 14 disposed within base 12 and the other of the electrodes 26 is electrically connected to a third electrical contact 28 disposed within base 12.
  • a current-limiting resistor 30 may be placed in series with one of electrodes 24 and 26 and its respective electrical contact.
  • the two light sources contained within envelope 12 are independent of one another unlike those disclosed in the prior art.
  • the dual-type light bulb 10 may be employed in a lamp fixture that accepts and is wired for conventional three-way filament light bulbs.
  • light bulb 10 of the present invention may be used in a three-way light socket that is wired such that current may be independently supplied to either the incandescent filament 18 or the glow-discharge lamp
  • the optically transmissive envelope 20 contains a noble gas such as xenon surrounding an incandescant filament 18 as is known in the art, and glow-discharge lamp 22 is contained within a separately enclosed envelope 32.

Abstract

L'invention concerne une ampoule électrique (10) dotée d'un culot (12) qui comporte au moins un premier (14), un deuxième (16) et un troisième contact (28) électrique. Une enveloppe à transmission optique (20), hermétiquement scellée au culot (12), renferme un gaz noble. Au moins un filament est disposé à l'intérieur de l'enveloppe à transmission optique (12) et est électriquement relié au premier (14) et au deuxième (16) contact électrique. Au moins une source de lumière électrique non incandescente est également disposée à l'intérieur de l'enveloppe à transmission optique (12). Cette source de lumière, qui fonctionne indépendamment du filament, (18) est électriquement reliée au premier (14) et au troisième (28) contact électrique.
